    You will have to go in an clear the cmos.

    Open your case and check for the cmos jumpers

    when looking for the
    jumper / dipswitch the label of that switch can be anything;
    however, in most cases will be labeled CLEAR - CLEAR CMOS - JCMOS1 - CLR -
    CLRPWD - PASSWD - PASSWORD - PWD.

    Tell me what you see. and get back

Open the case and find the CLEAR CMOS jumper, change it's position and let it stay for about 20 seconds, the revert it to the original position.

You can instead unplug the pc from the power outlet, open it, remove the battery from the moderboard(it's a coin sized battery that's easy to see and usually has some latch to slide it out),let the pc rest for about 2 minutes or so, and put the battery back into  its place. close the pc side door, and Voilà! it should be back to life.
it will take a little longer than usual on its first boot and might beep a few, it's all ok.

My dell desktop asking for a password


If you want to create a new Basic Input/Output System (BIOS) password on a Dell Optiplex 745, reset the password. Resetting the password also applies if you want to remove an existing BIOS password. BIOS passwords are used to add an additional level of security to your machine. Without the correct BIOS password, your Dell Optiplex 745 will not complete the boot process. The password can be reset whether you know your current password or not.

Turn off your Dell Optiplex 745. Start the computer. Press "F2" the moment the Dell logo appears on the screen. You will only have two to three seconds to press the key. Enter your BIOS password. Navigate to the "Exit" screen. Select the "BIOS Password" setting. Enter your BIOS password and a new password if desired. Do not enter anything in the "New Password" box if you want to remove the BIOS password completely. Press "Enter" to save your password settings. Reset Forgotten Passwords Turn off your Dell Optiplex 745 and remove the power cord from the computer. Disconnect any external hardware and cables. Slide the release latch located on the back of your Optiplex 745. Lift the cover as you slide the latch. Hold the cover firmly and pivot it back on the hinges. Remove the cover from the hinges. Find the "PSWD" jumper on the motherboard. This is a two-pin jumper and should be clearly labeled. Use a flashlight and magnifying glass if you have trouble locating it. Remove the jumper from the motherboard. Replace the cover and slide it into place until the latch snaps into place. Reconnect the power cable and restart your computer. Shut down the computer after it has completely restarted. Disconnect all cables and remove the cover again. Replace the PSWD jumper. Replace the cover. Reconnect all cables and restart your computer.

There should be a setting in the BIOS to ignore errors so you can get it to boot. It's usually set to halt on all errors by default.

Hi,

The BIOS password may be cleared from a Dell Optiplex by removing the password jumper (PSWD) from the motherboard.
Can click the link below to see how its done or follow the steps below :--

  • Remove the jumper plug from pins 1 and 2.
  • Place the jumper plug on pins 2 and 3 and wait approximately 5 seconds.
  • Replace the jumper plug on pins 1 and 2.

Admin Password


You need to clear the CMOS settings. To do this, you will need to set the CMOS jumper to the clear state (if the motherboard has one) OR remove the CMOS battery located on the motherboard. After waiting a few seconds, replace the battery and power the PC back on and attempt to enter the BIOS.

The battery will be a large flat battery similar to what you would find in a watch.

Check your BIOS. If it rebooted chances are it might work if you change the way the BIOS sees and boots the devices. Try rebooting without the flash drive in. What happens?
